A formal complaint has been filed with the U.S. Senate Ethics Committee over the refusal by the Foreign Relations Committee to investigate a wide range of scandals, including "Chinagate" and "Filegate," in Sen. Hillary Clinton's past while she was questioned for her appointment to secretary of state.

Larry Klayman, known for pursuing Clinton scandals in the 1990s as founder of the government watchdog Judicial Watch, filed the complaint after the Foreign Relations Committee ignored his request.

"I hereby file an ethics complaint against Senator John Kerry and Senator Richard Lugar and the other members of the Senate Foreign Relations Committee concerning their failure to conduct an investigation into the demonstrable unethical history of Senator Hillary Rodham Clinton," said Klayman's letter, addressed to Sens. Barbara Boxer and John Cornyn of the Select Committee on Ethics.
